Application filed February 17,

This invention relates to record-o-phones p for recording and reproducthe provision the machine its reels inof the wire type ing sound and has for its object of means to automatically stop when the windings on any of crease to a certain diameter.

In brief the device consists of a pair of flexible and rigid contact members, fastened to a block adapted to slide in a base, means to ascertain the position of the contact mem- "bers with respect to the reels and means to swing the structure out of the way so the be taken oflt' their hubs. For a more etailed understanding of the 1 invention attention is now called to the drawings in which a. referred embodiment is shown illustrated. Tn these drawings like reels can readil parts are designated by like reference char acters in all the views. Fig. 1 is a front view of a record-o-phone having a set of circuit closers attached thereto adjacent the reels. Fig. 2 is anenlarged section on line 2-2 of Fig. 1.

Fig. 3 is a section on line 3'-3 of Fig.2. Fig. 4 is a section on line 4-4 of Fig. 2. Fig. 5 is a top view partly in section of a modified form of the invention.

Fig. 6 is a section on line 6-45 of Fig. 5. v Fig. 7 is a section on line 7-7 of Fig. 5. Referring. now to the drawings in detail, numeral 1 designates the usual'base of the record-o-phone, 2 the usual reels and 3 the reel windings. 35 of circuit closers left is shown in the circuit closer 4:. e The circuit closer at the at the right is shown swung out of the way so the reel can be readily taken off the hub. As both circuit closers are alike one will be described.

The circuit closer iconsists of hinged on a bolt tained in its operative position by a spring base is a block 9 t0 a base 5 ap 8. Movable within the which are attached a rigid member 10 and aflexible member 11 and at the top of the said members are contact points 12 and 13. sulating .the members 10v and 11 from the composed of a non-conducting material. 'Fasten'ed to the said flexible and rigid members are a pair of conductors 15 and -16 which lead to a switch (not.

The members 10 and 11 are normally urged "apart bythe spring 17 and to prevent the members from spreading apart too much collars 18 and 19 are provided. The inner collar 18 is composed of an insulating mater al. Thespring 17 is insulated from the member 11 by an insulating plate 20.

To retain the slidable block in any desired *ROSltlOIl a set screw21 is provided. As noticed in Fig. 2 a set of graduations is engrayed on the upper face of the base 5." C0- actlng with the graduations and attached to the slidable block. 9 is a pointer 23.

' The operation of this device is as follows: The'pointer 23 is set in a position which will correspond to almost the largest diameter of the windings 3. When the windings have reached its maximum amount the flexible member 11 will be bent towards the rigid member 10, complete an electric circuit and operate a switch (not shown) for stopping the motor (not shown).

The circuit closer can way asnoticed in Fig. 1 to the right so the reel can be takenoif and slipped on the reel hub. Integral with the base 5 is a stop 24 for limiting the turning movement 0 circuit closer.

In-Fi s. 5, 6, and 7 form 0 the device. structure of that shown in exception-of the means to move As will be noticed in Figs. 6 and 7 the under portion of the" block 25 is. formed with teeth 26 and engaging the teeth is a small .gear 27'housed in a recess mounted on a shaft 29. For moving the block 25 to the right or to the left the knob 30 is turned accor 'ng to the direction of movement desired.

Having thus described my invention, what I desire to secure by United States Letters Patent is:
